  • Recently, there has been a tendency for accidents occurring in manufacturing to lead to serious accidents and serious industrial accidents and to extend to community disasters. In accordance with the Third Plan (2015-2019) of the National Security Management Plan, the Safety Administration announces and promotes improvement measures to minimize industrial accidents and disasters. In the case of industrial accidents from KOSHA 2015 to 2017, the accident rate of the metal-related manufacturing industry is 1.57%, which is more than three times higher than the average 0.50% of all industries. As a result of investigating the causes of disasters, 72% of workers were found to be caused by unsafe behaviors. In addition, insecure behaviors are closely related to safety consciousness, and a survey on safety consciousness was conducted for workers in this field. Safety consciousness improvement has the affirmative effect on accident prevention and it is a factor to reduce accidents.

  • This study was performed to see whether neurobehavioral tests was affected by the exposure-free time in the workers chronically exposed to organic solvents. Thirty-four female workers were participated and four items among neurobehavioral core test battery of World Health Organization, including digit span, Santa Ana Dexterity, digit symbol and Benton Visual Retention, were administered to the workers. Test was conducted three times-preshift on Monday, preshift on Weekday and during shift on Weekday-per person and the interval of tests was 2 weeks. Digit span forward, Santa Ana Dexterity, digit symbol, and Benton Visual Retention showed significant decrements by performing time, especially during shift on Week-day versus preshift on Monday and preshift on Weekday. In addition, the score at preshift on Weekday was significantly lower than preshift on Monday, in preferred Santa Ana Dexterity and digit symbol. Generally, those who were exposed to high concentration, over 50 years and under 6 years of education showed marked decrease of score at during shift. So, it would be desirable that neurobehavioral test is conducted at preshift on Monday and items related to short term memory could be considerable to be done at preshift on Weekday.

  • 기술의 발전은 사회에 많은 변화를 일으키고 있다. 또한 기술의 발전은 예술 영역에 있어서도 형식과 내용에 많은 변화와 영향을 주고 있다. 컴퓨터 아트, 인터액티브 아트, 뉴 미디어 아트라고 불리는 새로운 예술 장르들이 탄생하였으며 예술가들은 다양한 기술과 접목하여 새로운 작품을 만들어 내고 있다. 뉴 미디어 아트의 중요한 특징 중 하나는 상호작용성인데 이것은 예술작품, 예술가, 그리고 관람자의 수용방식에 결정적인 변화를 가져왔다. 즉 뉴미디어 아트서의 예술작품은 완성태가 아닌 과정(process)으로 주어지고, 예술가는 작업의 초안자 또는 작업의 맥락을 규정하는 자로 규정되며, 작품과 관람자간의 상호작용이 무엇보다 강조된다. 그러나 기존의 뉴 미디어 작품에서 일어나는 상호작용성은 미리 계산된 범위 안에서 일어나는 제약이 있기에 진정한 상호작용성이라고 보기 힘들다는 비판도 있다. 이런 상호작용성은 공학적 세계관에 갇힌 닫힌 시스템으로서의 상호작용성이라고 말하며 미적인 상호 작용성의 도구로서 열린 시스템으로서의 새로운 작품의 필요성을 제시한 예술가들이 있다. 본 논문은 이러한 예술가들의 발자취를 따라 더 본질적인 미학적 상호작용성에 대한 고민과 함께 그에 따른 새로운 상호작용적 예술인 행동지향적 예술로서 인공지능, 인공생명 아트에 대하여 살펴보고자 한다.

  • Attempts were made in this paper to compare the practice of protective actions for information of patients' medical treatment between hospital administrators who do not make direct contact with patients and occupational therapists who usually do. The comparison between jobs in charge showed that occupational therapists did not practice much protective actions for information of patients' medical treatment ($3.52{\pm}.809$) compared to hospital administrators ($3.92{\pm}.724$), even though the former had received regular education about protection, management and supervision of patients' medical information more often ($3.17{\pm}1.129$) than the latter ($3.16{\pm}1.037$). In spite of the fact that occupational therapists were exposed frequently to the danger of revealing medical information in the process of their job performance through talks and communications with patients, they displayed relatively little concern for and awareness of keeping information of medical treatment from being leaked by them. It is thus suggested to promote awareness of medical staff to protect medical information by means of flexible educational system for each occupational group, periodical monitoring, continuing public relation, training and quality control for protection of medical information, as well as routine self-examination of such practice.

  • The construction safety policy of Korea requires safety reviews at design stages, which affect the perceptions and attitudes of the workers toward safety. Despite this heightened social interest in safety, there is no related research in the field of landscape architecture. This study entails a review of the status of landscape construction accidents in Korea and an assessment of landscape engineers' perception of construction safety climate and safety behaviors. A survey of landscape constructors and designers was performed, and the obtained data were statistically analyzed. The results indicate the following: (1) More than half of the accidents which are registered in CSI occurred in apartment houses ordered by the private sector in the type of facility and planting works in the landscaping process; (2) Landscape designers were better aware of safety than landscape constructors. Among them, safety attitude, work risk, work participation, and work pressure were statistically significant; Apart from the statistical significance, landscape designers recognized the importance of safety highly but they tended to have a relatively low perception of specific safety behaviors. (3) Lastly, landscape constructors attributed less importance to safety review during the design stage compared to other items.

  • Objective : This study examined the characteristics of the literature involving a single-subject research design among positive behavior support intervention studies to improve problem behavior in children with autism spectrum disorders and assess the quality level. Methods : This is a literature study, and the targets of analysis were nine single-subject research papers published between 2011 and 2020. The subject papers were analyzed by dividing them into general characteristics and the qualitative levels according to the content of the research method. Results : Analysis of analyzing the contents of the study showed that the subjects were preschool and elementary school-age children at the same ratio. Furthermore, the study design involved mostly the middle and multiple baseline designs among the behaviors. All papers presented social validity, intervention fidelity, and observer reliability. Problem behaviors included self-injury and aggression behaviors, disturbing behaviors, and seat break-away behaviors, while the most dependent variables were measured through partial interval recording. As a result of confirming the intervention effect, the effect was confirmed in intervention, maintenance, and generalization. All analysis studies showed high-quality levels. Conclusion : This study confirmed the content and qualitative level of the thesis that applied the single-subject research design among positive behavior support intervention studies for problem behaviors of children with autism spectrum disorders. Positive behavior support intervention, an evidence-based intervention for children with autism spectrum disorders, was confirmed an effective intervention for autism spectrum disorders.

  • A person's behavioral recognition is the recognition of what a person does according to joint movements. To this end, we utilize computer vision tasks that are utilized in image processing. Human behavior recognition is a safety accident response service that combines deep learning and CCTV, and can be applied within the safety management site. Existing studies are relatively lacking in behavioral recognition studies through human joint keypoint extraction by utilizing deep learning. There were also problems that were difficult to manage workers continuously and systematically at safety management sites. In this paper, to address these problems, we propose a method to recognize risk behavior using only joint keypoints and joint motion information. AlphaPose, one of the pose estimation methods, was used to extract joint keypoints in the body part. The extracted joint keypoints were sequentially entered into the Long Short-Term Memory (LSTM) model to be learned with continuous data. After checking the behavioral recognition accuracy, it was confirmed that the accuracy of the "Lying Down" behavioral recognition results was high.

  • This study analyzes human error of workers performing simple repetitive tasks, and in order to prepare preventative measures, 486 people were used as subjects. The results of the study are like the following. First, the biggest cause of human error showed to be the worker himself in $77.8\%$ of the cases, machinery showed to be the cause in $16.3\%$ of the cases and management showed to be the cause in $6.0\%$ of the cases. The results show that most of the human error occurred due to the worker performing simple repetitive tasks and the human errors showed to be caused more by bad ergonomics and long hours rather than by problems with machinery. In addition, the area with the highest rate of human error showed to be the Human Information Processing System with Task Input Error being the highest with $46.9\%$, followed by Judgement and Memory Error with $36.4\%$ and Recognition Verification Error with $16.7\%$. Although fully automated tasks may reduce the rate of human error we must focus on lowering the rate of problems arising from spontaneous errors caused by workers performing simple repetitive tasks by continuously renewing plans and budgets in order to standardize tasks by incorporating cyclic positioning according to experience and positional exchange and by inspecting the workplace to increase efficiency of the workers.
